SELF-IGNITER.

SPECIFICATION forming part of Letters Patent No. 708,279, datedSeptember 2, 1902. Application filed February 6, 1902. Serial No.92,775. (No model.)

have invented certain new and useful Improvements in Self-Igniters, ofwhich the following is a specification.

This invention relates to a self-igniter which insures a quick ignitionof the gas when the gas-cock is opened. The igniter may be readilyfitted to the suspending-hook of the mantle and may readily be removedand replaced when worn.

In the accompanying drawings, Figure 1 is a perspective view of myimproved igniter,

showing it applied to a mantle. Fig. 2 is a perspective View of amodification; Fig. 3, a side view of a further modification of theigniter, and Fig. 4 a side View of a modification 0f the bail.

The letter a represents a bail or cross-arm which is adapted to besuspended from the hook I), carrying'the mantle 0, so that the bailextends horizontally across the top of The bail is provided at itscenter with a loop a, in order to engage the hook and is of a length toproject with its ends a short distance beyond the mantle. These ends maybe either bent downward, as at a Fig. 1, or they may be looped, as at aFig.

4.. From each end of the bail depends a platinum wire d, carrying anumber of spaced igniting-pellets e of the class which become red-hotwhen brought into contact with illu- Between the pellets 6 each wire dis encircled by a platinum spiral f,

extending from pellet to pellet. Thus tho wire d constitutes a carrierfor the pellets and at the same time a core for the intervening spirals,so that the latter are held against displacement.

It will be seen. that the platinum wires and spirals,.as well as thepellets, are arranged along both sides of the mantle and in. closeproximity thereto. The gas on being turned on will glow the pellets,vandthe latter will in turn render the platinum Wire and the coilincandescent, so as to ignite the gas quickly. If the igniter becomesworn, it may be readily lifted ofi the hook and replaced.

In Fig. 2 I have shown a cruciformbail ct a with four platinum wires inlieu of the single bail shown in Fig. 1.

In Fig. 3 the suspending-loop a is replaced by a socket a that isprojected over the end of hook I).

What I claim is- A self-igniter composed of a bail, platinum wiresdepending from the bail ends, a number of spaced igniting-pelletscarried by the platinum wires, and platinum spirals that encircle thewires intermediate the pellets and extend from pellet to pellet,substantially as specified.
